Supernatural Season 7 Episode 10

Rufus: Seriously, though, Bobby, how come...?
Bobby: Dog with a bone, Rufus.
Rufus: No, I really want to know, man--why no kids?
Bobby: Ain't that deep. Dad was a mean drunk. I figured I'd be just like him. And, hey, look, I was right. No sense passing on the legacy.
Rufus: You're too hard on yourself. You're more of a cranky drunk.

Dean: We're coming for you. And not just to hurt you--to kill you. You understand me?
Dick Roman: Come on, Dean, I can't be killed.
Dean: You're gonna wish you could, then.
Dick Roman: (laughs) That's some conviction. You'd really crush it on the motivational circuit.
Dean: You're either laughing because you're scared or you're laughing because you're stupid. I'll see you soon, Dick.

Reaper: Bobby... you've helped. You got handed a small, unremarkable life, and you did something with it. Most men like you die of liver disease, watching Barney Miller reruns. You've done enough. Believe me.
Bobby: I don't care.
Reaper: Why?
Bobby: Because they're my boys.

Bobby: Well that's a load of crap. Who the hell were you to say?
Ed Singer: I'm your father. And you show your father respect.
Bobby: The day he deserves it. You drunken bully. Punching women and kids, is that what they call fatherhood in your day?
Ed Singer: You deserved it. Believe me, you were nothing but ungrateful.
Bobby: I was a kid! Kids ain't supposed to be grateful. They're supposed to eat your food and break your heart, ya selfish dick! You died and I was still so afraid I'd turn into you, I never even had kids of my own.
Ed Singer: Good. You break everything you touch.
Bobby: Well, as fate would have it, I adopted two boys and they grew up great. They grew up heroes. So you can go to hell!
